The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the table for Jaconé over the next couple of weeks. It’s a bit of a mixed bag, but there’s some serious light at the end of the tunnel if you can wait.
The forecast starts quiet and a bit messy. For the first several days, we’re seeing small, weak swell with mostly onshore or cross-offshore winds. We’ve got a long wait for anything truly worthwhile. The water’s sitting at 72°, which is bang on average for this time of year, no surprises there.
Thursday the 30th and Friday the 31st are write-offs. Small waves, poor conditions; I wouldn’t bother paddling out. Saturday the 1st of August shows a slight lift, with a 3ft swell from the south, period of 12 seconds, and moderate offshore wind from the NE first thing. That’s decently clean, and combined wave energy is moderate at 301, but it’s only a 2/5 on the quality scale – small and a bit weak. The afternoon gets blown out by a fresh E breeze. Sunday the 2nd and Monday the 3rd are tiny and mostly unappealing, though Monday morning has glassy conditions with a 4ft east swell—period is a short 6 seconds, so it’ll be weak and crumbly.
Tuesday the 4th through Friday the 7th start to show a bit more consistency, with generally clean conditions in the mornings and some moderate offshore breezes. Swell stays between 3ft and 5ft, mostly from the south, with periods around 10-13 seconds. The combined energy on Tuesday morning hits 439, which is solidly moderate, but the waves themselves are still on the smaller side. These are decent sessions for an intermediate, but nothing to get overly excited about. Crowds are possible here sometimes, so expect company on the better days.
Then it gets quiet again over the weekend of the 9th and 10th, with onshore winds and poor surf. The standout window is the following week. Wednesday the 12th of August is the one everybody’s been waiting for. The swell pumps up to 5ft from the south, with a 14-second period, and a gentle offshore breeze from the ENE. That’s groundswell energy, and it shows – combined energy is a beefy 1180 (strong). The conditions are labelled “excellent surf for experienced surfers.” This is the best on offer, but at 5ft it’s getting a bit chunky; hold onto your lunch if you’re a beginner. That long period also means it’ll be lining up better on the reefs and points than a straight beach break.
The following days drop back down but stay surfable. All in all, you’ve got a lot of small, average days to sit through, but that window around August 12th is the real gem. Be patient.
Stay wet,
Rusty

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
